我建议您使用https://github.com/Shopify/shopify_python_api库
此外，要检索某个时间段内的订单，我建议您使用graphql而不是REST api。
给你们举个例子

{
    orders(query:"created_at:>='2022-01-01T00:00:00BST' AND created_at:<='2022-12-31T23:59:59BST')", sortKey: CREATED_AT, reverse: true, first: 20) {
        pageInfo {
            hasNextPage
        }
        edges {
            cursor
            node {
                createdAt
                name
                lineItems(first: 20) {
                    pageInfo {
                        hasNextPage
                    }
                    edges {
                        cursor
                        node {
                            variant {
                                title
                                inventoryQuantity
                            }
                            sku
                            title
                            quantity
                        }
                    }
                }
            }
        }
    }
}

shopify.Session.setup(api_key=client_id, secret=client_secret)
if password: # depending if you have a password (private app) or access token (custom/public app)
    shopify_session = shopify.Session(store, api_version, password)
else:
     shopify_session = shopify.Session(store, version=api_version, token=access_token)
shopify.ShopifyResource.activate_session(shopify_session)

def retrieve_orders():
    with open('query.graphql', 'r') as fp:
        query = fp.read()
    result =  json.loads(shopify.GraphQL().execute(query))
    # ...
    return resutl['edges']

请记住，您必须处理结果中的分页（这与REST API相同），并且要检索超过120天的订单（我可能是错的，但情况类似），您需要特定的权限。
